Since her Harley Quinn was the crazy bright spot in Suicide Squad, we know Margot Robbie is a great actress who easily pulls off out-sized characters. Her starring turn in I, Tonya—a drama about scheming wild-child skater Tonya Harding—hasn't even finished filming yet but we've already got footage proving Margot is totally nailing the role.

This snippet is from a scene in which Harding appears to be yelling at another character and insisting that the competition in which she's skating is fixed. There's a lot of anger but Robbie's perfectly-pitched Midwestern American accent makes it so on-point as to be funny, too.
